About Fleetzero
Fleetzero develops marine energy, propulsion and autonomy systems for commercial and defence vessels. Its Leviathan modular battery system scales from individual modules to megawatt installations, while a 3.8-megawatt-hour containerised version packages energy into a swappable marine format. The company integrates batteries with electric or hybrid propulsion from vessel design through commissioning.
OctoDrive adds route planning, sensor fusion and multi-vessel control using inputs such as GPS, AIS, inertial navigation, radar and cameras. OctoPod provides a shore-based teleoperation station, and suitcase-sized OctoBox supplies retrofit command hardware aboard the vessel. Together these products support crew assistance, remote operation and progressively more hands-off navigation, with a stated limitation that the current teleoperation design targets uninspected vessels rather than every regulated ship class.

Timeline
Events
- 2026-06-16 - Product Launch - Fleetzero launches OctoDrive marine autonomy stack
Fleetzero launched the OctoDrive marine autonomy stack alongside its marine power products. OctoDrive supports autonomy software, OctoPod provides a full-scale teleoperated command center and OctoBox packages retrofit autonomy hardware. The stack targets commercial autonomy and remote operation for existing and newbuild vessels.
